Palladium-Catalyzed Coupling of sp²-Hybridized Tellurides

Abstract

Vinylic tellurides are of importance due to their useful behavior as synthons and intermediates. Recently, the use of these compounds in place of vinylic halides or triflates in the palladium-catalyzed cross-coupling reaction has emerged as a powerful tool in the preparation of conjugated enyne and enediyne. In this way, vinylic tellurides can behave as aryl or vinyl carbocation equivalents. This review focuses on methods that involve the use of vinylic tellurides in palladium-catalyzed cross coupling reaction.
